[0002] The current fitness equipment has a single performance, and can only exercise in a fixed position during use, lacking a sense of realism in motion
Although there are also some exercise bikes that can really exercise on the market, the design is complicated and the scope of use is also limited. In addition, there are some special exercise bikes, such as rowing exercise bikes. Although this bike can get more intense exercise , but the main exercise is the legs and arms, and the exercise effect on the waist is less

The invention discloses a hydraulic exercise bicycle, which comprises a frame. A hydraulic drive mechanism is arranged above the frame. The hydraulic drive mechanism includes a double-piston rod hydraulic cylinder. A one-way throttle valve is provided on the liquid flow path between the hydraulic cylinder and the double-piston rod hydraulic cylinder, the one-way hydraulic cylinder is hinged to the frame, the end of the piston rod of the one-way hydraulic cylinder is hinged to the lower surface of the pedal, and the pedal is away from the one-way One side of the hinged end of the hydraulic cylinder and the pedal is hinged with the fixed rod, and the fixed rod is fixed vertically to the vehicle frame. The piston rod of the double-piston rod hydraulic cylinder is fixed with the screw rod. Between the shafts, the ratchet meshes with the outer output shaft, the screw rod is set in the sleeve, the outer output shaft is set in the sleeve and is relatively fixed with the sleeve, the outer output shaft is set on the end cover and can rotate relative to the end cover, One end of the sleeve away from the double piston rod hydraulic cylinder is fixedly connected to the wheel axle.
Description
technical field [0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a hydraulic fitness bicycle. Background technique [0002] The performance of the current fitness equipment is single, and it can only be exercised at a fixed position during use, which lacks the sense of reality of exercise. Although there are also some exercise bikes that can really exercise on the market, the design is complicated and the scope of use is also limited. In addition, there are some special exercise bikes, such as rowing exercise bikes. Although this bike can get more intense exercise , but the main exercise is the legs and arms, and the exercise effect on the waist is small. Contents of the invention [0003] In view of this, the present invention provides a hydraulic exercise bicycle to solve the deficiencies in the prior art. [0004] Technical scheme of the present invention is: [0005] A hydraulic exercise bicycle, comprising a fra...
